several defects:
-the power setting is wrong, the small tip holds well and does not imbalance the lighter when placed upright on a table for example (it stands but wobbly manner) I personally removed and the lighter takes better but little practice to set power (need a rod or knife end to push the metal tab)
-sometimes when you press the trigger, the flame does not go out (but gas) and it takes several tries to see the fire gush but it always comes out in the end.
-When the lighter has just been reloaded it happens that the flame does not stop when we stopped to pull the trigger, it is an important safety issue
-after refill the lighter, the flame is too powerful when used right after.
But this lighter still works, I will say that it is his money, but I advise you to invest in a more expensive lighter and better quality although it is more difficult to find.
